Upon this cover plate'the metal plates is snitably securcd andrepresents tivo pages'of'an open boolg said plate bearing uponitssurface at opposite sides of center suitable advertising matter."This plate'at its upper and loweredges and at" its approximate centerhas-spaced tongues '9' struck "therefrom-and"between these tong'ues'fthe"'redu'cedendsof a metal strip indicated n10 are adapted to betrictional'lj engag'edfl To one edge of th is strip the platenrepresenting a book leaf is hinged as-at-'*12, said plate likewisebearing on its opposite 'side" faces, suitable advertising matter.

Within the housing or casing theentire mechanism for turning the hingedleaf 11 in relatively opposite directions at the end of suitable timeintervals to display the advertisements carried thereby, is contained.This mechanism includes a member 13 which is pivotally mounted as at 14upon a suitable supporting bracket 15 fixed to the bottom wall of thecasing 5. This member has parts extending at substantially 90 withrespect to each other from the pivot 14 and each terminating inanarcuately curved arm 16. These arms are adapted to be moved throughaligned openings indicated at 17 in the front plate 7 of the casing andthe plate 8 secured thereon which are located at relative opposite sidesof the hinge 12 of the leaf 11.

The bracket member 15 is provided at its central portion with ahorizontally extending slot having a central curved section 18 and thestraight end sections 19 in alignment with each other. The edges 20 ofthe member 13 extending at right angles to each other are respectivelydisposed in coinciding relation with one edge of the respective endportions 19 of this slot in the different positions assumed by themember 13.

The member 13 is automatically operated by suitable thermdelectricallycontrolled means contained within the casing 5. In the embodiment of theinvention herein illustrated, this means includes an expansible andcontractable resistance wire 21 which is turned around a'selies ofsheaves or pulleys 22 losely mounted on the shafts 23 mounted insuitable spaced brackets 24 secured to the bottom wall of the casing 5at the opposite ends thereof.

One end of this resistance wire is fixed as at 25 to a fixed part on oneof the shafts 23. The other end of the resistance-wire is suitablyattached to an insulating piece 26 with which one end of a coil spring27 is connected, the other end of said spring being attached to one ofthe brackets 24. Current is supplied from the house circuit through thewires 28 and 29, the wire 29 being connected with the resistance element21 adjacent its fixed end 25. The other wire 28 is connected with onepole or terminal by a suitable type of snap switch indicated at 30, theother pole of which is connected by wire 31 with resistance element 21adjacent to its opposite end. As shown in Fig. 9, the switch includes apivotally movable contact carrying member 32 which in one position isadapted to connect the pole terminals and thereby close the circuit.This member is operated by and is also movable independently of themember 33 which ispivotally mounted within the switch casing as at 34.To this member 33, the upper end of a rod 35 is suitably connected, thelower end of said rod cooperating with the edges 20 of the pivotedmember 13 and being movable in the horizontal slot 1819 of the bracketplate 15.

This rod is connected with the upper strand or the resistance wire 21 bya sleeve of insulating material 36 loosely engaged on said rod andcarrying a set screw 37. The upper part of the sleeve is also providedwith a slot 38 intersecting the bore thereof and opening on the upperend of the sleeve, said slot at its base being provided with a recess 39in one side wall. This slot receives the resistance wire strand and upontightening the set screw 3'? against the rod 35, the strand is bent andforced into the recess 39 while the sleeve 36 is thus rigidly secured inany desired adjusted position along the rod 35 in spaced relation to thepivot 34.

The circuit wires 28 and 29 may extend through a suitable outlet bushingindicated at 40 in the back of base wall of the casing 5 for connectionwith a suitable plug for engagement in a socket or wall outlet. The

rear wall of the casing is also preferably provided with a ventilatingopening shown at 41 so that the heat generated by the resistance wire 21may find a free outlet.

The rear wall of the casing may be extended below the bottom wallthereof and provided with suitable supporting members indicated at 42and to the rear of the casing an adjustable leg or prop 43 is pivotallyattached at its upper end as at 44 so as to support the casing in adesiredinclined'position. To retain the prop 43 in its adjustedposition, I may provide the chain indicated at 45 passing through asuitable eye 46 on the prop 43 and having one of its ends permanentlyattached to the rear wall of the casing, and said casing wall beingprovided with a hook indicated at 47 with which the chain adjacent toits other end may be connected.

In the operation of the device as above described, in the position ofthe rod 35 as seen in Figs. 1 and 90f the drawings, the switch is open.Assuming that this operation has just taken place, and due to theresistance generated heat, the wire 21 has fully expanded while thespring 21 is contracted, as the resistance wire cools, it will contractand gradually reduce in length, thereby pulling upon the spring 27 andexpanding the same. The rod 35 is thus also moved to the left from theposition shown in Fig.1, and during the first part of this movement, thelower end of said rod will move freely in the right hand end portion 19of the slot in the bracket 15 from the position shown in Fig. 7 of thedrawings. V

The snap switch as shown in Fig. '9 is of the spring toggle type andduring this first part of the movement of the rod 35, the movable switchmember remains in the open position while energ is being stored in thetoggle spring. Continued con- Cil quickly throw the movable switchmember 32 to the closed position'which thereby also imparts a quickmovement to the lower end of the rod 35 which bears against one of theedges 20 of the member 13. As this end of the rod moves in the curvedpart 18 of the slot in the bracket member, the m mber 13 is moved fromthe position of 7 to the position shown in Fig. so that one of its arms16 is moved outwardly through the opening 17 and acts against thepivoted or hinged leaf 11 to move the same through an arc ofsubstantially 45 and from a position in parallel relation to plate 8 toa position. in a plane slightly beyond a 90 angle with respect theretoor past the center of gravity so that said hinge leaf 11 will then dropor fall to the dotted line position snown in Fig. 6 of the drawings.

Since the circuit has now been closed, the resistance wire 21 will againexpand and progressively with such expansion of the wire, the spring 27contracts, thus moving the rod 35 in the opposite direction, or towardsthe position of Fig. 1. In the first part of such movement, the lowerend of rod 35 moves to the right in the end portion of the slot inbracket and is engaged with the angularly extending edge of member 13,at which time the spring toggle of the switch operates to move theswitch member 32 to the open position, and continue the movement of rod35 to thereby operate the member 13 in the reverse direction and causethe other of the arms 16 thereof to engage the hinged leaf l1 and turnthe same to it former position.

These operations are then repeated a above described at the regularintervals 0 time sufficient to enable the advertising matter on thesurfaces of the movable leaf l1 and of the tired plate 8 to be read bythe ob- 5 server. The length of time elapsing between successiveoperations of the member 13 may be varied or changed within certainlimits by longitudinally adjusting the sleeve 36 along the rod 35towards or from the pivot 34.

From the foregoing description considered in connection with theaccompanying drawings. the construction of my improved advertisingdevice as well as the operation thereof and its several advantages inpractical use will be clearly understood. It will be seen that by theprovision of electrical re sistance control means for actuating the leafturning movement of the kind above described, it is possible to verycompactly house or arrange all of the operating parts within arelatively shallow housing or casing so that the device may be mountedand arranged in a relatively small space in a show window for use inconnection with display advertising. Also, in view of the very simpleform and construction of the several elements employed, it will beapparent that the device can be manufactured and sold at relativelysmall cost and will also be posi 've and reliable in its operation andnot liable to get out of order.

I have herein shown and described an embodiment of the invention which Ihave found to be entirely satisfactory i practical use. Nevertheless, itwill be und t the essential features of my invention in susceptible ofmore or less modification in form, construction and relative arrangem ntof its various pa-rs, and I therefore, reserve the privile e ofresorting to all such legitimate and alterntive embodiments thereof asmay be fairly incorporated in the spirit and scope of the invention asclaimed.
